Amazon workers in Staten Island warehouse voted for a union earlier this month. Amazon is seeking to overturn the election, having argued the vote was tainted by organizers. The nascent Amazon Labor Union, or ALU, has said it wants longer breaks, more time off and a higher minimum hourly wage. Experts say delays for a contract can frustrate such union campaigns and undermine employee confidence in organized labor. If Amazon pursues a protracted legal battle before agreeing to a contract, the number of employees at the warehouse who voted for the union would also likely dwindle. One way workers can push back is by employing a strike, which, of course, carries its own risks. The union is ready to pressure the company through the news media by engendering public sympathy. . . .
